SF6 Gas emissions for High Speed Rail

SF6 Gas emissions for High Speed Rail

The sulphur hexafluoride gas (SF6) is an electronegative gas and has a strong tendency to absorb free electrons. The gas captures the conducting free electrons in the arc to form relatively immobile negative ions. This loss of conducting electrons in the arc quickly builds up enough insulation strength...
